Driver Qualification Files & Drug Testing

49 CFR § 391.51(b) lists it: the employment application, the motor vehicle record pulled when you hired the driver, the road test certificate or an accepted equivalent, the MVR from your annual inquiry, a note recording the annual review, and the medical examiner's certificate. § 391.51(a) requires a file for every driver you employ. Missing DQ files are one of the fastest ways to fail an audit.

At least once every 12 months, from every licensing authority where the driver held a CMV license during that period, under 49 CFR § 391.25(a). Separately, § 391.25(b) requires you to review that record against the disqualification standards in § 391.15 and put a note of the review in the file. Those are two different obligations, and carriers routinely do the pull and skip the review.

49 CFR § 382.305(b) sets the minimum annual rates at 10 percent of average driver positions for alcohol and 50 percent for controlled substances. The FMCSA Administrator can adjust them by notice, so the rate is worth confirming each year. We run the consortium and handle the selections.

No. 49 CFR § 382.301(a) prohibits letting a driver perform any safety-sensitive function until you have a verified negative controlled-substances result from the MRO or C/TPA. A limited exception exists under § 382.301(b) for drivers coming from a qualifying program. Putting a driver in a truck on a pending result is a violation, not a gray area.

Yes. 49 CFR § 382.701(a)(1) requires a pre-employment query before the driver performs a safety-sensitive function. § 382.703(a) requires the driver's written or electronic consent first, and you must keep that consent for 3 years from the date of your last query. We register you and run the queries.
